Abstract
Gastro-oEsophageal Cancers (GECs) are severe diseases whose management is rapidly evolving. The European Society of Surgical Oncology (ESSO) is committed to the generation and spread of knowledge, and promotes the multidisciplinary management of cancer patients through its core curriculum. The present work discusses the approach to GECs, including the management of oligometastatic oesophagogastric cancers (OMEC), the diagnosis and management of peritoneal metastases from gastric cancer (GC), the management of Siewert Type II tumors, the importance of mesogastric excision, the role of robotic surgery, textbook outcomes, organ preserving options, the use of molecular markers and immune check-point inhibitors in the management of patients with GECs, as well as the improvement of current clinical practice guidelines for the management of patients with GECs. The aim of the present review is to provide a concise overview of the state-of-the-art on the management of patients with GECs and, at the same time, to share the latest advancements in the field and to foster the debate between surgical oncologists treating GECs worldwide. We are sure that our work will, at the same time, give an update to the advanced surgical oncologists and help the training surgical oncologists to settle down the foundations for their future practice.

Abstract
PURPOSE Surgery provides vital services to diagnose, treat, and palliate patients suffering from malignancies. However, despite its importance, there is little information on the delivery of surgical oncology services in Tanzania. METHODS Operative logbooks were reviewed at all national referral hospitals that offer surgery, all zonal referral hospitals in Mainland Tanganyika and Zanzibar, and a convenience sampling of regional referral hospitals in 2022. Cancer cases were identified by postoperative diagnosis and deidentified data were abstracted for each cancer surgery. The proportion of the procedures conducted for patients with cancer and the total number of cancer surgeries done within the public sector were calculated and compared with a previously published estimate of the surgical oncology need for the country. RESULTS In total, 69,195 operations were reviewed at 10 hospitals, including two national referral hospitals, five zonal referral hospitals, and three regional referral hospitals. Of the cases reviewed, 4,248 (6.1%) were for the treatment of cancer. We estimate that 4,938 cancer surgeries occurred in the public sector in Tanzania accounting for operations conducted at hospitals not included in our study. Prostate, breast, head and neck, esophageal, and bladder cancers were the five most common diagnoses. Although 387 (83%) of all breast cancer procedures were done with curative intent, 506 (87%) of patients with prostate and 273 (81%) of patients with esophageal cancer underwent palliative surgery. CONCLUSION In this comprehensive assessment of surgical oncology service delivery in Tanzania, we identified 4,248 cancer surgeries and estimate that 4,938 likely occurred in 2022. This represents only 25% of the estimated 19,726 cancer surgeries that are annually needed in Tanzania. These results highlight the need to identify strategies for increasing surgical oncology capacity in the country.

Abstract
Background Leukemia encompasses various subtypes, each with unique characteristics and treatment approaches. The challenge lies in developing targeted therapies that can effectively address the specific genetic mutations or abnormalities associated with each subtype. Some leukemia cases may become resistant to existing treatments over time making them less susceptible to chemotherapy or other standard therapies. Objective Developing new treatment strategies to overcome resistance is an ongoing challenge particularly in Low and Middle Income Countries (LMICs). Computational studies using COMSOL software could provide an economical, fast and resourceful approach to the treatment of complicated cancers like leukemia. Methods Using COMSOL Multiphysics software, a continuous flow microfluidic device capable of delivering anti-leukemia drugs to early-stage leukemia cells has been computationally modeled using dielectrophoresis (DEP). Results The cell size difference enabled the micro-particle drug attachment to the leukemia cells using hydrodynamic focusing from the dielectrophoretic force. This point of care application produced a low voltage from numerically calculated electrical field and flow speed simulations. Conclusion Therefore, such a dielectrophoretic low voltage application model can be used as a computational treatment reference for early-stage leukemia cells with an approximate size of 5 μm.

Abstract
This paper is a transcript of the 29 th Eugene N. Myers, MD International Lecture on Head and Neck Cancer presented at the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) in 2020. By the end of the 19 th century, the survival rate in treated patients was 10%. With the improvements in surgical techniques, currently, about two thirds of patients survive for > 5 years. Teamwork and progress in surgical reconstruction have led to advancements in ablative surgery; the associated adjuvant treatments have further improved the prognosis in the last 30 years. However, prospective trials are lacking; most of the accumulated knowledge is based on retrospective series and some real-world data analyses. Current knowledge on prognostic factors plays a central role in an efficient treatment decision-making process. Although the influence of most tumor- and patient-related prognostic factors in head and neck cancer cannot be changed by medical interventions, some environmental factors-including treatment, decision-making, and quality-can be modified. Ideally, treatment strategy decisions should be taken in dedicated multidisciplinary team meetings. However, evidence suggests that surgeons and hospital volume and specialization play major roles in patient survival after initial or salvage head and neck cancer treatment. The metrics of surgical quality assurance (surgical margins and nodal yield) in neck dissection have a significant impact on survival in head and neck cancer patients and can be influenced by the surgeon's expertise. Strategies proposed to improve surgical quality include continuous performance measurement, feedback, and dissemination of best practice measures.

Abstract
AbstractWorldwide, the capacity of healthcare systems and physician workforce is woefully inadequate for the surgical treatment of cancer. With major projected increases in the global burden of neoplastic disease, this inadequacy is expected to worsen, and interventions to increase the workforce of surgeons who treat cancer and strengthen the necessary supporting infrastructure, equipment, staffing, financial and information systems are urgently called for to prevent this inadequacy from deepening. These efforts must also occur in the context of broader healthcare systems strengthening and cancer control plans, including prevention, screening, early detection, safe and effective treatment, surveillance, and palliation. The cost of these interventions should be considered a critical investment in healthcare systems strengthening that will contribute to improvement in the public and economic health of nations. Failure to act should be seen as a missed opportunity, at the cost of lives and delayed economic growth and development. Surgeons who treat cancer must engage with a diverse array of stakeholders in efforts to address this critical need and are indispensably positioned to participate in collaborative approaches to influence these efforts through research, advocacy, training, and initiatives for sustainable development and overall systems strengthening.

Abstract
Background Surgery is the main treatment for the majority of solid cancers. Studies investigating surgical interventions are a critical asset in improving patient health outcomes. We aim to analyze the temporal and spatial distribution of the surgical treatment of Brazil’s 5 most common types of cancer. Methods The selected cancers were stomach, colorectal and rectosigmoid junction, bronchial and lung, breast, and prostatic. Surgical data were collected from the DATASUS database from 2013 to 2019. Statistical analyses included linear regression tests with a significance level of .05. Results From 2013 to 2019, 19.72% of the diagnoses of all cancers were treated surgically. Only breast cancer didn’t have a significant linear increase in surgeries ( P = .702). Prostatic cancer had the highest annual increase rate and breast the lowest. Analyzing the Brazilian regions, the Southeast had the highest incidence of oncological surgeries, and the Midwest had the lowest. Discussion Brazil’s surgical oncology scenario is progressing positively through the analyzed period. The analysis of the 5 most common types of cancer in Brazil and their progression over the years provides an idea of the cancer surgery capacity in Brazil. There were disparities between the Brazilian regions in all types of cancer. Our study is the first step to better comprehending cancer care in Brazil and the access issues that some areas have. With that, it will be possible to provide better care to cancer patients needing surgical treatment.

Abstract
Background To describe the status quo and trends in the global burden of all cancers caused by secondhand smoke during 1990–2019. Methods Data on cancer associated with secondhand smoke were extracted from the Global Heath Data Exchange. Cancer burden was measured by cancer-related deaths, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs). Results In 2019, age-standardized rates of death, DALYs and YLLs among the cancer population globally caused by secondhand smoke were 1.60, 38.54 and 37.77, respectively. The proportions of these in the total cancer burden for all risk factors combined decreased slightly from 1990 to 2003 and then increased from 2004 to 2019. In 2019, >50% of the cancer burden was concentrated in men aged 55–75 years and women aged 50–70 years. Between 1990 and 2019, there was an increase in age-standardized rates of death, DALYs, YLDs and YLLs among those aged ≥70 years. The age-standardized YLDs rate attributable to secondhand smoke was higher among women; it decreased in men but increased in women, causing a wider gap between the sexes. A greater cancer burden was mainly seen in North America in 1990 and Europe in 2019. Reductions in the annual rate change of cancer burden were found mainly in North America and Oceania, while increases were found in Africa and Asia. In 2019, high–middle- and middle-SDI countries had higher age-standardized rates of deaths, DALYs, YLDs and YLLs than the global level. During 1990 and 2019, the largest decline in cancer burden was seen in high-SDI countries, while middle- or low-SDI countries experienced increases in all age-standardized rates. Conclusions Cancer burden attributable to secondhand smoke is concerning given the increasing health loss and differences in distribution of cancer burden worldwide. Further studies are needed to investigate the causes of disparities in cancer burden attributable to secondhand smoke and to improve understanding of the contribution of secondhand smoke to the burden of different types of cancer.

Abstract
Sestrin 2, a highly conserved stress-induced protein, participates in the pathological processes of metabolic and age-related diseases. This p53-inducible protein also regulates cell growth and metabolism, which is closely related to malignant tumorigenesis. Sestrin 2 was reported to regulate various cellular processes, such as tumor cell proliferation, invasion and metastasis, apoptosis, anoikis resistance, and drug resistance. Although sestrin 2 is associated with colorectal, lung, liver, and other cancers, sestrin 2 expression varies among different types of cancer, and the effects and mechanisms of action of this protein are also different. Sestrin 2 was considered a tumor suppressor gene in most studies, whereas conflicting reports considered sestrin 2 an oncogene. Thus, this review aims to examine the literature regarding sestrin 2 in various cancers, summarize its roles in suppression and tumorigenesis, discuss potential mechanisms in the regulation of cancer, and provide a basis for follow-up research and potential cancer treatment development.

Abstract
INTRODUCTION Surgical oncology is a defined specialty within the European Board of Surgery within the European Union of Medical Specialists (UEMS). Variation in training and specialization still occurs across Europe. There is a need to align the core knowledge needed to fulfil the criteria across subspecialities in surgical oncology. MATERIAL AND METHODS The core curriculum, established in 2013, was developed with contributions from expert advisors from within the European Society of Surgical Oncology (ESSO), European Society for Radiotherapy and Oncology (ESTRO) and European Society of Medical Oncology (ESMO) and related subspeciality experts. RESULTS The current version reiterates and updates the core curriculum structure needed for current and future candidates who plans to train for and eventually sit the European fellowship exam for the European Board of Surgery in Surgical Oncology. The content included is not intended to be exhaustive but, rather to give the candidate an idea of expectations and areas for in depth study, in addition to the practical requirements. The five elements included are: Basic principles of oncology; Disease site specific oncology; Generic clinical skills; Training recommendations, and, lastly; Eligibility for the EBSQ exam in Surgical Oncology.

A systematic review of modeling and simulation approaches in designing targeted treatment technologies for Leukemia Cancer in low and middle income countries. MATHEMATICAL BIOSCIENCES AND ENGINEERING : MBE 2021; 18:8149-8173.

Abstract
Virtual experimentation is a widely used approach for predicting systems behaviour especially in situations where resources for physical experiments are very limited. For example, targeted treatment inside the human body is particularly challenging, and as such, modeling and simulation is utilised to aid planning before a specific treatment is administered. In such approaches, precise treatment, as it is the case in radiotherapy, is used to administer a maximum dose to the infected regions while minimizing the effect on normal tissue. Complicated cancers such as leukemia present even greater challenges due to their presentation in liquid form and not being localised in one area. As such, science has led to the development of targeted drug delivery, where the infected cells can be specifically targeted anywhere in the body. Despite the great prospects and advances of these modeling and simulation tools in the design and delivery of targeted drugs, their use by Low and Middle Income Countries (LMICs) researchers and clinicians is still very limited. This paper therefore reviews the modeling and simulation approaches for leukemia treatment using nanoparticles as an example for virtual experimentation. A systematic review from various databases was carried out for studies that involved cancer treatment approaches through modeling and simulation with emphasis to data collected from LMICs. Results indicated that whereas there is an increasing trend in the use of modeling and simulation approaches, their uptake in LMICs is still limited. According to the review data collected, there is a clear need to employ these tools as key approaches for the planning of targeted drug treatment approaches.

Abstract
BACKGROUND The Lancet Commission on Global Surgery (LCoGS) recommended an annual surgical rate at which low- and middle-income countries (LMICs) could achieve most of the population-wide benefits of surgery. However, condition-specific guidelines were not proposed. To inform rates of surgery for cancer, we sought to assess the current met and unmet need for oncologic surgery in Ghana. METHODS Data on all operations performed in Ghana over a one-year period (2014-15) were obtained from representative samples of 48/124 first-level and 12/16 referral hospitals and scaled-up for nationwide estimates. Procedures for cancer were identified by indication. Using modified LCoGS methodology with disease prevalence, Ghana's annual rate of cancer surgery was compared to that of New Zealand to quantify current unmet needs. RESULTS 232,776 surgical procedures were performed in Ghana; 2,562 procedures (95%UI 1878-3255) were for cancer. Of these, 964 (37%) were surgical biopsies. The annual rate of procedures treating cancer was 2115 surgeries/100,000 cancer cases, or 21% of the New Zealand benchmark. Cervical, breast, and prostate cancer were found to meet 2.1%, 17.2%, and 32.1% of their respective surgical need. CONCLUSIONS There is a large unmet need for cancer surgery in Ghana. Cancer surgery constitutes under 2% of the total surgeries performed in Ghana, an important proportion of which are used for biopsies. Therapeutic operative rate is deficient across most cancer types, and may lag behind improvements in screening efforts. As cancer prevalence and diagnosis increase in LMICs, cancer-specific surgical capacity must be increased to meet these evolving needs.

Robot-assisted endoscopic inguinal lymphadenectomy: A review of current outcomes. Asian J Urol 2020; 8:20-26. [PMID: 33569269 PMCID: PMC7859461 DOI: 10.1016/j.ajur.2020.08.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 05/11/2020] [Accepted: 05/28/2020] [Indexed: 12/27/2022] Open
Abstract
Objective To review the role of robot-assisted endoscopic inguinal lymphadenectomy (RAIL) in the management of penile cancer. Methods A PubMed search for all relevant publications regarding RAIL series up until August 2019 was performed using the keyword “robotic”, “inguinal lymph node dissection”, and “penile cancer”. Weighted mean was calculated in the largest series for all outcomes using the number of patients included in each study as the weighting factor. Results We identified 23 articles, of note the three largest series that included 102, 27, and 20 RAIL in 51, 14, and 10 patients, respectively. Saphenous vein was spared in 88.93% of RAIL cases in these series and node yield was 11.42 per groin; 35.28% of patients had positive pathological nodes. The weighted mean of operative time was 87.98 min per RAIL and the estimated blood loss was 37.08 mL per patient. The mean length of hospital stay was 1.29 days and the drain was kept in place for 17.02 days; the major complication rate was only 5.31% in these series. The mean follow-up was 33.46 months with a recurrence-free survival of 96.33%. Conclusion The literature regarding RAIL describes promising results, although it has shorter follow-up and higher costs when compared to historically series from the open approach. Initials series reported lower cutaneous complications compared to conventional approach, without compromising oncological outcomes. However, long-term results and larger trials are crucial to validate those findings.

Abstract
Squamous cell carcinoma of the oral cavity and oropharynx have been used synonymously and interchangeably in the world literature in the context of head and neck cancers. As the 21st century progresses, divergence between the two have become more evident, particularly due to evidence related to human papillomavirus-associated oropharyngeal squamous cell carcinoma. As such, the American Joint Committee on Cancer recently published the 8th edition Cancer Staging Manual, serving as a continued global resource to clinicians and researchers. Through changes in staging related to T and N clinical and pathologic classifications, the new system is expected to influence current management guidelines of these cancers that have distinct anatomic and etiopathogenic characteristics. This article aims to review such impactful changes in a time of critical transition of the staging of head and neck cancer and how these changes may affect clinicians and researchers worldwide.

Abstract
Cancer is a worldwide epidemic and represents a major threat to human health and survival. Reactive oxygen species (ROS) play a dual role in cancer cells, which includes both promoting and inhibiting carcinogenesis. Tea remains one of the most prevalent beverages consumed due in part to its anti- or pro-oxidative properties. The active compounds in tea, particularly tea polyphenols, can directly or indirectly scavenge ROS to reduce oncogenesis and cancerometastasis. Interestingly, the excessive levels of ROS induced by consuming tea could induce programmed cell death (PCD) or non-PCD of cancer cells. On the basis of illustrating the relationship between ROS and cancer, the current review discusses the composition and efficacy of tea including the redox-relative (including anti-oxidative and pro-oxidative activity) mechanisms and their role along with other components in preventing and treating cancer. This information will highlight the basis for the clinical utilization of tea extracts in the prevention or treatment of cancer in the future.

Abstract
Background The organisation and systematisation of health actions and services are essential to ensure patient safety and the effectiveness and efficiency of cancer care. The objective of this study was to analyse the structure of cancer care envisaged in Brazilian norms, describe the types of accreditations of cancer services and their geographic distribution, and determine the planning and evaluation parameters used to qualify the health units that provide cancer care in Brazil. Methods This observational study identified the current organisation of cancer care and other health services that are accredited by Brazil’s national health system (SUS) for cancer treatment as of February 2017. The following information was collected from the current norms and the National Registry of Health Establishments: geographic location, type of accreditation, type of care, and hospital classification according to annual data of the number of cancer surgeries. The adequacy of the number of licensed units relative to population size was assessed. The analysis considered the facilitative or restrictive nature of policies based on the available rules and resources. Results The analysis of the norms indicated that these documents serve as structuring rules and resources for developing and implementing cancer care policies in Brazil. A total of 299 high-complexity oncology services were identified in facilities located in 173 (3.1%) municipalities. In some states, there were no authorised services in radiotherapy, paediatric oncology and/or haematology-oncology. There was a significant deficit in accredited oncology services. Conclusions The parameters that have been used to assess the need for accredited cancer services in Brazil are widely questioned because the best basis of calculation is the incidence of cancer or disease burden rather than population size. The results indicate that the availability of cancer services is insufficient and the organisation of the cancer care network needs to be improved in Brazil.

Abstract
OBJECTIVE To identify and characterize the interventions that aimed to improve cancer treatment and follow-up care in socially disadvantaged groups. To summarize the state of the art for clinicians and researchers. METHODS We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were randomized controlled trials and quasi-experimental studies with a control group (usual care or enhanced usual care) conducted in Organization for Economic Co-operation and Development (OECD) member countries and published until 2016. RESULTS Thirty-one interventions were identified, the majority of which were conducted in the United States in patients with breast cancer. Most interventions aimed to decrease social inequalities based on ethnicity/race and/or socioeconomic level, with fewer interventions targeting inequalities based on geographical area. The most frequently assessed outcomes were quality of life (n = 20) and psychosocial factors (n = 20), followed by treatment adherence or satisfaction (n = 12,), knowledge (n = 11), pain management (n = 10), and lifestyle habits (n = 3). CONCLUSIONS The impact of interventions designed to improve cancer treatment and follow-up care in socially disadvantages groups is multifactorial. Multicomponent-intervention approaches and cultural adaptations are common, and their effectiveness should be evaluated in the populations of interest. More interventions are needed from outside the Unite States and in patients with cancers other than breast cancer, targeting gender or geographical inequalities and addressing key outcomes such as treatment adherence or symptom management.

Abstract
BACKGROUND In recent years, there has been an exponential increase in the global burden of cancer which has been associated with several factors including environmental influence, aging, diet, infectious agents, hormonal imbalance and chronic inflammation, among others. Cancerous cells utilize more glucose for its proliferation and survival than normal cells. Thus, the regulation of glucose consumption of cancerous cells through the inhibition of glucose transporter-4-protein (GLUT4) encoded by solute carrier family-2-member-4-gene (Slc2a4) by selected phytochemicals from Solanum xanthocarpum may serve as a new therapeutic candidate for the treatment of cancer. METHODS The seven identified potential inhibitors of GLUT4 from Solanum xanthocarpum were retrieved from PubChem database. Examination of their drug-likeness, toxicity prediction and molecular docking studies of these compounds with GLUT4 were carried out using online tools such as Molinspiration, PreADMET V.2.0 and Patchdock server. RESULTS The findings revealed that, five out of the seven compounds fulfil oral drugability of Lipinski's rule of five (RO5) while two slightly meet the criteria of RO5. Conversely, five of the compounds are predicted to be mutagen while the remaining two are predicted to be safe for the body. Additionally, stigmasterol glucoside has higher binding-affinity (7590) with GLUT4 when compared to doxorubicin (6600) the control. CONCLUSION These findings suggest that stigmasterol glucoside from Solanum xanthocarpum could be a promising therapeutic agent with better therapeutic efficacy than doxorubicin in the treatment of cancer via the inhibition of GLUT4.

Individualized metabolic profiling stratifies pancreatic and biliary tract cancer: a useful tool for innovative screening programs and predictive strategies in healthcare. EPMA J 2018; 9:287-297.

Abstract
BACKGROUND Pancreatic cancer (PC) and biliary tract cancer (BTC) are highly aggressive cancers, characterized by their rarity, difficulty in diagnosis, and overall poor prognosis. Diagnosis of PC and BTC is complex and is made using a combination of appropriate clinical suspicion, imaging and endoscopic techniques, and cytopathological examination. However, the late-stage detection and poor prognosis of this tumor have led to an urgent need for biomarkers for early and/or predictive diagnosis and improved personalized treatments. WORKING HYPOTHESIS There are two hypotheses for focusing on low-mass metabolites in the blood. First, valuable information can be obtained from the masses and relative amounts of such metabolites, which present as low-mass ions (LMIs) in mass spectra. Second, metabolic profiling of individuals may provide important information regarding biological changes in disease states that is useful for the early diagnosis of PC and BTC. MATERIALS AND METHODS To assess whether profiling metabolites in serum can serve as a non-invasive screening tool for PC and BTC, 320 serum samples were obtained from patients with PC (n = 51), BTC (n = 39), colorectal cancer (CRC) (n = 100), and ovarian cancer (OVC) (n = 30), and from healthy control subjects (control) (n = 100). We obtained information on the relative amounts of metabolites, as LMIs, via triple time-of-flight mass spectrometry. All data were analyzed according to the peak area ratios of discriminative LMIs. RESULTS AND CONCLUSIONS The levels of the 14 discriminative LMIs were higher in the PC and BTC groups than in the control, CRC and OVC groups, but only two LMIs discriminated between PC and BTC: lysophosphatidylcholine (LysoPC) (16:0) and LysoPC(20:4). The levels of these two LysoPCs were also slightly lower in the PC/BTC/CRC/OVC groups compared with the control group. Taken together, the data showed that metabolic profiling can precisely denote the status of cancer, and, thus, could be useful for screening. This study not only details efficient methods to identify discriminative LMIs for cancer screening but also provides an example of metabolic profiling for distinguishing PC from BTC. Furthermore, the two metabolites [LysoPC(16:0), LysoPC(20:4)] shown to discriminate these diseases are potentially useful when combined with other, previously identified protein or metabolic biomarkers for predictive, preventive and personalized medical approach.

Abstract
BACKGROUND AND OBJECTIVES Outcome data after surgery for cancer in Sub-Saharan Africa are insufficient. We aimed to describe the presentation and outcomes of patients with solid cancers managed at a tertiary hospital in Ghana. METHODS Records of cancer patients admitted to Komfo Anokye Teaching Hospital general surgery wards from 2013 to 2016 were reviewed for data on presentation, staging, management, and mortality. Patients discharged alive were followed-up by biannual telephone calls to establish their postdischarge status. Survival analysis was performed for patients with pathologic or radiologic confirmation of cancer and adequate staging. RESULTS A total of 343 patients were included. Of these, 76% were female. The most common diagnoses were breast 136 (40%), foregut 70 (20%), and colorectal 63 (18%) cancers. Cancer diagnosis was confirmed by pathology or radiology in 281 (82%) patients, but only 112 (40%) had adequate staging. Seventy-four (66%) patients were stage IV. Two-year overall survival for all 343 patients was 22% to 69%, depending on cancer site. Among those with adequate staging who were alive after postoperative 90 days, 3-year survival was similar for curative compared with palliative operations (P = 0.64). CONCLUSIONS Improved capacity for both therapeutic and palliative cancer care is needed to achieve better outcomes by more appropriate allocation of surgery with respect to the goal of treatment.

Abstract
Disparities in cancer control exist in low- and middle-income countries (LMICs). Many countries do not have cancer registries to record incidence, mortality and prevalence and are reliant on Globocan estimates of their cancer burden. Poorer cancer control within and between countries occurs in those living remotely from urban centres, those in a low socioeconomic group and some ethnic groups who have lifestyle and belief systems which impact on cancer control. High-income countries generally have population screening programmes for cervix, breast and bowel cancer. However, simpler forms of screening for cancer of the cervix like visual inspection with acetic acid have been shown to be feasible in developing nations. The widespread use of vaccines to prevent cancer has been achieved with the Hepatitis B vaccine but the human papilloma virus vaccine to prevent cancer of the cervix is largely only available in high-income countries. Access to and training of oncological surgeons in LMICs is limited, while 70% of patients in these countries cannot access radiotherapy. The World Health Organization has developed a list of essential medicines although access remains poor in LMICs. The United Nations has set targets for the control of non-communicable diseases to improve global cancer control.
